Those are lovely stitch patterns that you've chosen. I particularly like the lily of the valley, adorable. As long as you're doing swatches on these, why not try connecting them to test out the transitions? Seed stitch is a nice common background where you need it and since it lies flat, may help with transitions.
I'm really looking forward to seeing this in progress.

This is thrilling! I am working up a sample with the stitch patterns that I have chosen, transitioning from one to the next. I've done the ruffle and have progressed nicely into the brocade with the seed stitch in between; it is working out beautifully. Thank you so much.
